The International Union for the Conservation of Nature and Natural Resources (IUCN) currently lists the species as “Data Deficient”. However, it has been suggested that the species has declined by about 60% between the periods 1978–91 and 1991–2004. If the decline is shown to be an artifact or to have been transient, the species would then be classified as “Least Concern” whereas it would be classified as “Endangered” if it was demonstrated to be an actual decline. The Peru population was added to Appendix I of CITES in 1986 and withdrawn from it in 2001. The predicted substantial decline in the extent of Antarctic sea ice may dramatically effect krill populations and the Antarctic minke whale populations that depend on them.
